Two men who owned a San Antonio frozen food business have been indicted on charges of filing false tax returns and other crimes related to business dealings with shell companies they allegedly controlled overseas.

Robert Warren Scully and Kevin James Scully were named in a nine-count indictment filed by the U.S. attorney's office on July 7 but unsealed Wednesday after the men were arrested. Kevin Scully was arrested in Peoria, Ill., and Robert Scully in Santa Cruz, Calif.

The indictment says the two were owners of Gourmet Express, a San Antonio-based company that manufactured and distributed frozen skillet meals to grocers and other food outlets.

From April 2001 to July 2009, prosecutors allege, the Scullys conspired to conceal income and to mislead Internal Revenue Service officials about income they earned.

The indictment outlines a scheme in which the men are accused of using four shell companies in Thailand to inflate the cost Gourmet Express paid for shrimp and then siphoning off those excess costs to various bank accounts that they and their wives used for personal expenses.

Neither of the men nor their attorneys could be reached for comment Thursday.

Special agent Mike Lemoine, with the IRS' criminal investigations division, said the men posted $50,000 bond each after their initial hearings and agreed to wear an electronic monitoring device pending arraignment next month.

Robert Scully was described in the indictment as Kevin Scully's uncle and as the president and CEO of Gourmet Express. Their current addresses were not available.

Gourmet Express paid anywhere from 10 cents to 95 cents more per pound for shrimp because of the scheme, the indictment claims.

It also contends the pair filed false personal tax returns for themselves and their wives in 2003, 2004, 2005 and 2006 and that they caused a false return to be filed on behalf of the food company for 2006 taxes.

While the total amount of underreported income and other claims was not tabulated, Assistant U.S. Attorney Bill Harris said prosecutors contend the tally will reach the multimillion-dollar level.
